Abstract: A system for transferring data files between a host device and a secondary device can include a bridge device forming at least a portion of the secondary device. The bridge device can have a de-multiplex (de-MUX) data path with an input coupled to a host interface (I/F), a first output coupled to a storage I/F and a second output coupled to a processor I/F. A controller circuit can have control inputs coupled to receive configuration commands from the processor I/F and control outputs coupled to control terminals of the de-MUX data path. The controller circuit enables and maintaining a data path between the host I/F and the first output of the de-MUX data path for a predetermined number of data transfers in response to at least a first configuration data input.

Abstract: A USB control circuit for increasing USB endpoints includes a token detection circuit. The USB control circuit is configured to receive a first logical endpoint (LEP) address and a USB token. The token detection circuit is configured to determine a direction of a USB data transfer in accordance with a USB token type. The USB control circuit includes an endpoint configuration and status control logic circuit in communication with the token detection circuit. The endpoint configuration and status control logic circuit is configured to control configuration and status information associated with each of a plurality of LEP input buffers and LEP output buffers. The USB control circuit is configured to generate a second LEP address in accordance with a combination of the first LEP address and the determined direction to increase a quantity of LEPs without increasing a quantity of physical endpoint buffers of a USB device.
